• GreenScreen has issued its first Gold Standard carbon credits from verified emissions reductions generated through vessel retrofits.
• More than 350 ships are already enrolled, using efficiency upgrades to cut fuel use and CO2 emissions.
• Credit revenue is designed to help shipowners finance further retrofits while the sector waits for lower-carbon fuels and propulsion technologies to scale.

ClimeCo and Marsoft – Global Carbon Solutions have completed the first issuance of carbon credits under their GreenScreen shipping decarbonization project.

The credits were issued under the Gold Standard and are available for immediate delivery. They originate from verified emissions reductions achieved through energy-efficiency retrofits on commercial vessels.

The companies say the model can provide shipowners with an additional source of capital for upgrades. It also introduces a carbon-market financing mechanism into a sector facing growing pressure to decarbonize.

“This is the first issuance of shipping carbon credits using the latest methodology we developed in collaboration with the MIT Sea Grant Design Laboratory, marking a significant milestone for the industry,” says Arlie Sterling, President of Marsoft. “This issuance, together with others already underway, will deliver funding to accelerate the pace of retrofitting and decarbonization.”

Bridging shipping’s technology gap

International shipping accounts for approximately 3% of global greenhouse gas emissions. The International Maritime Organization is targeting net-zero greenhouse gas emissions from international shipping by or around 2050.

Meeting that objective will require major changes across fuels, vessel design, propulsion systems and port infrastructure. However, many next-generation technologies remain years from broad commercial deployment.

GreenScreen is focused on reductions that shipowners can pursue now.

More than 350 ships are already enrolled in the program. Participating vessels implement energy-efficiency retrofits that reduce fuel consumption and associated CO2 emissions.

Those reductions are measured and verified before carbon credits are issued under the Gold Standard framework.

Retrofits can include technologies that improve vessel efficiency without requiring operators to replace their fleets. For owners, that provides a pathway to reduce emissions from existing assets while longer-term technology options develop.

Carbon finance enters the retrofit equation

Financing remains one of the key obstacles to shipping decarbonization.

Shipowners must weigh the upfront cost of efficiency investments against fuel savings, vessel age, charter arrangements and future regulatory requirements. Carbon revenue can add another financial incentive to those investment decisions.

Under GreenScreen, revenue from credit sales can help offset retrofit costs and support additional upgrades.

That approach could become increasingly relevant as the maritime sector faces tighter emissions requirements and higher expectations from cargo owners, investors and lenders.

For carbon-credit buyers, the project also extends the voluntary carbon market into a difficult-to-abate sector where direct operational reductions can require significant capital.

“We’re proud to partner with Marsoft to bring our carbon market expertise to the registration and issuance of these high-quality, third-party verified credits,” says Erika Schiller, Chief Development Officer. “Together, we’re supporting shipowners in obtaining funding for more advanced retrofits and helping them navigate the voluntary carbon market with confidence.”

What executives and investors should watch

For shipping companies, GreenScreen provides another potential tool for funding near-term emissions reductions. Its commercial value will depend on credit demand, pricing and the continued credibility of verification standards.

For investors and cargo owners, the model creates a clearer link between carbon finance and physical efficiency improvements within operating fleets.

Governance will remain central. Shipping decarbonization increasingly sits at the intersection of international regulation, voluntary carbon markets and corporate supply-chain targets.

The first issuance also comes as companies face greater scrutiny over the quality of carbon credits and the extent to which credits support measurable, additional emissions reductions.

GreenScreen therefore enters the market at a critical point. Maritime companies need deployable solutions now, even as the industry prepares for a longer transition toward zero and near-zero emission fuels.

If retrofit-based credits can attract sustained demand, they could provide an additional pool of capital for one of the global economy’s hardest sectors to decarbonize.
